Below are some pictures of Andrew’s latest creation. This new 6.5” driver incorporates a much larger motor, larger diameter voice coil, and much longer excursion compared to the current LFR1100 woofer. After a lot of modelling on the FEA (Finite Element Analyses) software and a lot of physical samples built by Mike this new driver is complete. This new 6.5” woofer has much more power handling and stronger bass; which will complement the sheer output capabilities of the LFR1100 perfectly. Existing LFR1100s can be upgraded to these woofers. In addition there will be a new model that incorporates this driver called the M100, but more on that soon.

With the new drivers, will there be a corresponding DSP software "upgrade"? I would guess that with the new drivers, the system will be able to reach lower frequencies than before? Thus, possibly new software to take that into account?

Ah, so the "M100", which I've made facetious reference to in the past, is about to become reality.

Ian, the Thiele-Small parameters on the new woofers would be of interest, especially the max excursion and Fs.

Alex, a high quality 6 1/2" aluminum cone woofer might run about $60 as a guesstimate(we don't know the parameters), although some are over $100. Then of course there would also be software modifications needed.
